Metal bars on the windows (56 photos): choose beautiful and safe

If you live on the ground floor in an apartment building or in a private house, then the security problem worries you much more than the inhabitants of higher floors. After all, attackers can penetrate into the living quarters of an apartment, cottage or office not only through the door, but also through the windows. And as criminal statistics show, it is through penetration through windows and windows that are located on the ground floor that the majority of apartment thefts are committed.

You can secure your home or office by installing metal welded or forged lattices on the windows, which, in addition to the protective, also have a decorative function, sometimes being a real example of the art of forging. In the article, we will consider how to choose the right metal grilles for windows and what their types are.

Features

What features are inherent in metal bars designed to protect windows:

• The metal grill is a construction made of special impact resistant steel with an admixture of carbon.
• Each window grill has several basic steel elements. These are corners, pipes, flat strips that strengthen the structure, and an iron rod, as the basis of the entire structure.
• The thickness of the rod is from 10 to 20 mm. The standard size is 12-16 mm. A rod is never hollow. It is always completely all-metal. This monolithic design enhances product reliability. Welded structures are always made of rods.
• Carbon steel is not resistant to corrosion, so gratings are usually powder coated or, less commonly, painted with enamel. Sometimes, especially in the manufacture of decorative structures, patina and even gilding, bronzing and silvering techniques are used.

Manufacturing techniques

How exactly are metal grilles for windows made? There are two main techniques - forging and welding. More details:

Welded

Features:

• It is clear that in this case, the rods are welded to each other.
• With this technique, mainly protective grilles are made using simple straight elements.
• Inexpensive option, has a low decorative value, but reliable and durable.
• Welded gratings are often coated with enamel, since when uncovered they make a depressing impression.

Forged

• A much more decorative option implies beautiful elements, elegant lines and aesthetics.
• Due to the difficulty of performing a higher price.

Types of Gratings

Consider what options for metal gratings are available today and their features:

Protective

• This is the so-called ordinary grid of uniform cells - sometimes even a structure that repels its appearance. Primitive, but at the same time extremely reliable. Protective grilles are most often welded.
• The main thing here is not external beauty, but reliability.
• These types can vary by the thickness of the metal rod and the size of the cells. The smaller the cell, the more reliable the protection. But even less light will enter the room.
• Few make out residential apartments with such a grid. Most often they are intended for office buildings, banks, storages and archives.

Decorative

• The most beautiful and graceful of all kinds.They can represent real works of art of forging, have various decorative elements and details.
• The cells here are of irregular shape, the whole lattice is a certain composition, and the cells are part of this composition, they obey it. At the same time, the cell size can be quite large, if required by the drawing.
• Despite the reduced level of protective functions, forged lattices cost more than welded ones. The fact is that creating such a highly artistic work is much more difficult than a primitive mesh horizontal-vertical design. This is a job for a true master, whose prices correspond to the skill.

Protective and decorative

A compromise option combining good protective qualities and good decorative ones is the most popular option that people most often choose for their windows.

Types of opening

On this basis, there are 3 types of grilles: sliding, swing and stationary. Let's consider them in more detail:

Sliding

This option has a special device that allows you to move the grate if necessary, folding it in half. The presence of such a function sometimes allows to open the windows wide open in sunny weather, and then re-install the grille. Features:

• By the principle of operation they resemble a screen. The most difficult option in the engineering sense.
• It has a significant drawback - it does not prevent glass breaking and frame damage, is not suitable for a summer residence or houses where they do not live permanently.
• Locked.
• They are rarely decorative, because the folding design does not allow for the implementation of many interesting elements and techniques.

Swing

It also provides the ability to open the grilles, but only with the help of swinging open - like a shutter. Features:

• This option can open / close both outward and inward. Here, every real estate owner sees how he will be more comfortable. Usually open towards the street.
• There are one or two wings. For small windows, you can use a single-wing design, but for large windows, of course, only double-winged.
• Sashes open quite easily. A child will also cope with this, so this option is the safest in case of fire. It allows you to easily leave the room.
• Great for giving.
• In order to secure the house, hinged windows are locked with special locks.
• The cost of this option is higher than the stationary one. Fire safety regulations require its mandatory installation on one of the windows.

Stationary

Another name is deaf or monolithic. Everything is clear here - this is the most common and simple form - they do not add up and are not removed in any way. Installed once, they will “decorate” the window constantly. But this is the most reliable option of all. Stationary welded or forged gratings are almost impossible to open, crack. More features:

• They completely cover the window openings, are very firmly fixed, are installed “for centuries”. The ends of the metal pins are "walled" into the walls, the frames are welded firmly to them.
• Such a construction cannot be removed or damaged without special tools and corresponding noise.
• A significant minus is fire safety - because through the windows in case of fire it will be impossible to leave the room.
• They have the lowest cost, since it is easiest to make and install these types of gratings. You can also install it with your own hands - if you have some skills and the right tools.
